This isn't without cost, as it means you need either a new connection to do another DB request in parallel or a MARS connection. Too much for a comment really
I noticed that if I use IEnumerable, when I debug and inspect "sel", which in that case is the IEnumerable, it katışıksız some interesting members: "inner", "outer", "innerKeySelector" and "outerKeySelector", these last 2 appear to be delegates.
The second method allows only List objects to be passed in; it will derece accept an array or a String object. Obviously, the first method is better because it is much more flexible and gönül be used in a much wider range of scenarios.

In C# 4 and earlier the object obj; is declared outside of the while loop, this changes the behavior of the loop when working with things that capture variables like anonymous functions.
The syntax (which you rarely see because there are prettier ways to do it) for moving through a collection that implements IEnumerable is:
The "inner" member does derece have "Animal" instances C# IEnumerable Temel Özellikleri in it, but rather "Species" instances, which C# IEnumerable Nerelerde Kullanılıyor was very strange for me. The "outer" member does contain "Animal" instances. I presume that the two C# IEnumerable Nerelerde Kullanılıyor delegates determine which goes in and what goes out of it?
It saf a good performance when you are iterating through big objects or collections because it does hamiş load the entire object to memory in order to make iteration.
IEnumerable describes behavior, while List is an implementation of that behavior. When you use IEnumerable, you give the compiler a chance to defer work until later, possibly optimizing along the way. If you use ToList() you force the compiler to reify the results right away.
This works for read-only access to a collection that implements that IEnumerable emanet be used with a foreach statement.
What US checks and balances prevent the FBI from raiding politicians unfavorable to the federal government?
The reason, of course, is that someone sevimli call the first method passing in an array object, a List object, a String C# IEnumerable Nasıl Kullanılır object, and so on — any object whose type implements IEnumerable.
C# dilinde, IEnumerator özellikle aşağıdaki kabilinden koleksiyonlar üzerinde bilgi kıraat ve kârlemlerinde yeğleme edilir:
